can be indwendentiy c (His-(5., ca 6% 1 U :1 010581 and a em a base thefiver k ma lithe? 0 adjusted position in a similar manner, as shown inour Patent #1,114,985, dated October 27, 1914, whereby each of the deckframes will be allowed to be adjusted independently in order to changethe inclination thereof so as to adjust the inclination of thesupporting surface carried thereby, which will be later described,whereby any one of the frames can be adjusted independently of the otherto allow the classifying surface to be adjusted to suit the class ofmaterial being sized.

The deck framesare provided with suitable bearings at each end in whichare mounted shafts 5 and (l carrying rollers 7 and 8 on which aremounted endless flexible belts 9, 10, 11 and 12 arminged to deliver thematerial progressively from the upper .belt to the lower belts, Thesebelts are preferably provided with longitudinally arranged corrugationsincreasing in depth from the upper edge toward the lower edge thereof,but it isof course understood that any form of belt having a roughenedsurface can be employed for carrying out the process of sizing thematerial.

Each of the shafts G is provided with a pulley 13 over which passes thedrive belt 14 driven by change-speed mechanism A subst'antially\ asshown in our companion Patent $21,114,935, in order that the speed ofeach belt can be cont-rolledl i Mounted intermediate the shafts 5 and 6in each of the deck frames, is a shaft 15 carrying an angular taperingroller 16 constructed substantially as disclosed in our Patent#1,114,935, dated October 27, 191 1. The shafts 15 carrying the angularrollers 16 extend outwardly beyond the upper side bar of the respectiveframes and are provided with beveled gears 17 which mesh with beveledgears 18 carried by shafts 19 mounted in suitable bearings; said shaftscarrying pulleys 20 over which pass drive belts 21 driven by achange-speed mecha nism B constructed substantially as disclosed in ourPatent #1,114,935, dated October 27, 1914, whereby the speed ofvibration. of the belts can be independently con trolled.

The construction of the several units as hereinbefore described, issubstantially the same and the description of one is sufficient for all,as each is operated in the same manner that the adjacent unit isoperated, but is under an independent control and from the foregoingdescription, it will be seen that a sizing apparatus is providedcomposed of a number of units capable of being adjusted independently inorder to change the inclination of the surface and that the speed oftravel ofthe belt and the vibration thereof can also be controlledindependently.

Arranged at the delivery end of each of the sizing surfaces 9, 10 and11, is a series of spaced deflecting baffles 22, disposed in such aposition to receive and deliver the sized particles from the uppersizing surface to the next lower sizing surface in such a manner thatthe particles are prevented from racing or bouncing.

The deflecting baffles 22 conform to the curvature of the roller overwhich the belts pass, but are spaced slightly theref: m and are arrangedas clearly shown in Figs. 2 and 3 forming a number of channels whichextend obliquely in order to receive the material and deliver the sameto the next succeeding surface at a higher point, aswill be laterdescribed. These baffles are'preferably formed of angled platessupported by any suitable means, not shown, in the position as disclosedin Figs. 1, 2 and 3.

By constructing a sizing apparatus composed of a series of units, havingdeflecting baffles arranged to receive and deliver the material from onesizing surface to another, the particles are caused to travel a greaterdistance over the sizing surface than would be the case with anapparatus without the deflecting battles, and by giving the baffles acrook at their lower ends, the movement of the particles is arrestedwhen they are delivered to the sizing surface so as tolprevent the samefrom racing or bouncing. The division of these baffles into narrowchannels facilitates the transfer of the particles from one sizingsurface to the next succeeding surface without altering materially thedegree of sizing, so far as the progress upon the preceding surface isconcerned, and at the same time, the particles are advanced anddelivered to the next succeeding surface at a higher point. This can bereadily understood by referring to the diagrammatic view illustrated byFig. 3, where the approximate inclination of the sizing surface is shownwith reference to the perpendicular line KK, the dotted line terminatingat M showing the travel of the particles through the deflecting baffies.

The particle N on reaching the roller travels from the point (30 to'tiland thence to 62 on the next succeeding surface, and is delivered at thepoint M, while if it was allowed an unrestricted line of travel underthe influence of gravity and the agitation of the sizing surface, itwould report at L.

A suitable apron is arranged at the delivery end of the sizing surface12 and is provided with a spaced bar Ql under which are adjustablymounted lingers 25 for de fleeting the sized particles delivered fromthe last sizing surface of the apparatus into suitable receptacles andit is of course understood that while we have shown such an apron forthis purpose, the same can be dispensed with and the sized particles de-'10 of the succeeding surface, progressively varying the speed oftransport upon the suc- -i 'cessive supporting surfaces, and separatelycollecting the separated sizes of material from the last supportingsurface.

8. The process of sizing material, consisting in transporting materialcomposed of grains of varying sizes on a series of successive supportingsurfaces inclined transversely to the direction of transportingmovement, and subjecting said material to gravitative impulses adaptedto deviate the components of said material from the direction oftransport in proportion to their respective sizes, delivering thematerial in distributed condition from one surface to progressivelyincreased extents of the succeeding surfaces, progressively varying saidgravitative impulses upon the successive supporting surfaces,progressively varying the speedof transport upon the successivesupporting surfaces due to delivery from one surface to the next, andseparately collecting the separated sizes of material from the lastsupporting surface.

9. In a machine for sizing solid material, a series of independentlyadjustably mounted continuously moving sizing surfaces arranged in lineof continuous movement and inclined transversely to the direction ofcontinuous movement, means for transporting material discharged from theend of one continuously moving surface in distributed condition toprogressively increased extents of the succeeding surface, progressivelyvary- 45 ing the speed of travel of the successive continuously movingsurfaces, and means for separately collecting the separated sizes ofmaterial discharged from the last supporting surface.

'10. In a machine for sizing material, a series of continuously movingsizing surfaces arranged in line of continuous movement andinclinedtransversely to the direc tion of continuous movement, means fortransferring material in distributed condition from the end of onecontinuously moving surface to the next succeeding surface so as toadvance the material in its trans- 'ferring movement, progressivelyvarying 60 the speed of travel of the progressively moving surfaces, andmeans for separately collecting the separated sizes of materialdischarged from the last supporting surface.

11. A machine for sizing material, composed of grains of varying sizes,comprising a series of successive continuously moving supportingsurfaces inclined transversely to the direction of the continuousmovement,'

means for vibrating said surfaces to cause the components of saidmaterial to deviate from the line of continuous movement in proportionto their respective sizes, means for transferring material in itsdistributed condition from one surface to progressively increasedextents of the succeeding surface, means for driving the successivecontinuously moving surfaces at different rates of speed, means forprogressively varying the inclination of said surfaces, and means forcollecting the different sizes of material discharged from the lastsurface.

12. A machine for sizing solid material, composed of grains of varyingsizes, comprising a series of successive continuously moving supportsinclined transversely to the direction of continuous movement, means forvibrating said supports to cause the compo nents of said material todeviate from the line of continuous movement in proportion to theirrespective sizes, means for progressively varying the speed of movementof said supports, a series of spaced ed fleeting baflies arranged at theend of each of said supports for transferring material in itsdistributed condition from one surface to a higher point on the adjacentsurface, and means for collecting the separate sizes of material fromthe last supporting surface.

13. In a machine for sizing solid material, a series of laterallyinclined and longitudinally progressing separating surfaces, means fortransferring material in distributed condition from one surface to theadjacent surface so as to advance-the material in its transferringmovement, mechanism for im parting agitativc n'iovel'uent to saidsurfaces, progressively varying the speed of travel of the progius ivelymoving surfaces, and means for separately collecting the separated sizesof material discharged from the successive sui'iporting surfaces.
